          Abstract

          Foram determinados a composição química e os valores de energia metabolizável aparente (EMA) e energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn) de seis alimentos de origem vegetal utilizando-se o método de coleta total de excretas. Utilizaram-se 252 pintos de corte machos da linhagem Ross, com 21 dias de idade, distribuídos em um delineamento inteiramente casualizado, com sete tratamentos (uma ração-referência e seis rações-teste), seis repetições e seis aves por unidade experimental. Os alimentos avaliados foram milho (MI), milho de alta gordura (MAG), farinha de gérmen de milho integral (FGMI), soja integral tostada (SIT), casca de soja (CS) e farelo de soja de alta proteína (FSAP) com 50% PB. Os alimentos avaliados foram incluídos nas rações-teste em 40 e 25% da ração-referência, para alimentos energéticos e protéicos, respectivamente. Os valores para EMA, em kcal/kg de matéria natural, dos alimentos MI, MAG, FGM, SI, CS e FSAP foram de 3.402, 3.627, 3.019, 3.419, 814 e 2.070 e os de EMAn, de 3.393, 3.595, 2.935, 3.279, 741 e 1.984, respectivamente.

          The chemical composition, the apparent metabolizable energy (AME) and apparent metabolizable energy corrected by nitrogen (AMEn) of six feed of vegetal origins were determined by the total excreta collection method. A total of 252 male broiler chicks of the lineage Ross with 21 days of age were distributed in a completely randomized experimental design, with seven treatments (one basal reference diet and six test diets), six replicates and six birds per experimental unit. The evaluated feeds were: corn (CO), high oil corn (HOC), whole corn germ meal (WCGM), toasted whole soybean (TWSB), soybean hulls (SH), high protein soybean meal (HPSM) with 50% crude protein. The evaluated feeds were included in the diets-test in 40% and 25% of the reference diet, for the energy and protein feeds, respectively. The values of AME, in kcal/kg of as fed, for the feeds CO, HOC, WCGM, TSB, SH and HPSM were 3.402, 3.627, 3.019, 3.419, 814 and 2.070 and the AMEn values were: 3.393, 3.595, 2.935, 3.279, 741, and 1.984, respectively.
